IMPROVEMENT lN LUBRICATORS FOR JOURNAL-BOXES.

Specification forming part of Letters Patent No. 217,884, dated July 29,1879; application filed November 22, 1878.

To all whom it may concern:

Be it known that we, CHARLES H. LEONARD and WILLIAM B. HIOK, ofWilkesbarre, in the county of Luzerne and State of Pennsylvania, haveinvented a new and Improved Lubricator for J ournal-Boxes, of which thefollowing is a specification.

The object of this invention is to enable the lubricating material to befed to the journal and bearings evenly and without waste.

The invention will first be described in connection with the drawings,and then pointed out in the claim.

In the accompanying drawings, forming part of this specification, Figure1 ma transverse section of a journal-box furnished with our improvement.Fig. 2 is a longitudinal section of the same.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, the pillow-block of the journal-box isrepresented by A, the cap thereof is shown at B, and the bolts forconnecting the two parts together are represented by O O. The brassesare indicated by D D, and the journal by E, all of which, in the main,are of the old and well-known form of construction.

An oil-reservoir, F, is made on the top of the cap B, either by castingor fitting thereto. This reservoir is provided with a hinged lid, a. Thebottom of the oil-reservoir is provided with a slot, b, whichcommunicates with another slot, 0, immediately underneath, in the topbrass, D. The slotc is a little longer than the one above, so that theparts 0 e of the bottom, forming the ends of the slot I), projectslightly over the slot c.

G represents a roller, made of metal, wood, or other suitable material,longer than the slot 12, which is placed in the slot 0 in the brass D,and fits easily therein.

When the cap B is -placed on the pillowbloek, the parts 6 c, projectingover the slot 0, confine the roller in the said slot, but do notinterfere with the freedom of its movement.

The roller G rests upon thejournal E, and is, of course, frictionallyrotated by it.

Such is the description of the parts of our invention and their relationto each other. The manner of using it is as follows:

The lubricating material is placed in the reservoir F, whence it passesdown through the slot 1) and comes in contact with the roller G, whichpartially obstructs its free passage to the bearing and journal; out asthe journal rotates it rotates the roller, which takes up the lubricantin small but adequate quantities, and distributes it evenly on thesurface of the journal.

The fitting of the roller in the slot should depend largely upon thenature of the lubricant it is intended to use. For example, if an oil isused, the roller should fit snugly in the slot, so as to prevent a toofree passage of the oil; but if a compound is used more space must beleft, and the extent of the space must depend upon the solidity of thecompound.

We are aware that it is not new to employ a ball on a car-axle journalin connection with a tube leading to a separate oil-cup; but this isinconvenient, expensive, and entirely inapplicable to revolvingjournaIboXes, as in mining-car wheels.

We are also aware that a Wheel having shaft and journals with bearingshas been used to distribute oil on a car-axle journal; but

What we claim as new and of our inventio A lubricator for journalsprovided with a roller, Gr, arranged longitudinally in contact with thejournal, inclosed in a top slot of bear ing D, and connected by acorresponding slot directly with the oil-reservoir F, as shown anddescribed.
